Abstract
Anaerobic digestion (AD) of animal manure to produce biogas (methane) fuel has a wide variety of environmental benefits to air and water quality in addition to reducing greenhouse gas (GHG) emissions. In addition, the resulting biogas fuel and digestate products can help meet the energy needs and provide revenue to the farm. This case study explores the potential benefits and drawbacks of implementing an AD system at the Aurora Organic Dairy (AOD) High Plains Complex in Gill, Colorado. The project is envisioned as digester located at the AOD Complex with a single feed stream of manure from the Complex. The project would be implemented by a third-party contractor who would build and operate the system and pay the dairy a fraction of the profits, in addition to providing by-products such as digestate solids and liquids for fertilizer.
